i was curious, so i pulled out the engine analyzer, and this is what it says--

using the above cams and my engine combo:

mj cam pk hp/tq 540/541, avg 416/476 10"vac at idle on 110lsa

ed cam pk hp/tq 533/533, avg 417/478 12.2"vac at idle on 111lsa

neither cam liked a tighter lsa, losing most power in the lower range, especially below 3700rpm, while gaining 1 or 2 hp/tq at the top.

the above was with 1.7 ratio on the mj cam and 1.6 on the ec cam. i put the 1.7 ratio in for the ec cam and it didn't like it, showing:

ed cam pk hp/tq 514/537, avg 405/469 11.9"vac at idle

using the 1.7 on the exhaust didn't have any effect.

i was surprised, i knew i was giving up pk power with the ec cam, but the avg was the same or better. this was in the 3000-6150rpm range btw for both cams. the 1.7 ratio really killed the top end of the ec cam.
